Ehtylene is used to ripen certain fruits, such as bananas and tomatoes. It
is naturally produced by apples and many other fruits. That's why consumers
are warned not to package apples and bananas together. The bananas will
respond to the ethylene from the apples by over-ripening rapidly.

I don't believe the strawberry industry uses ethylene because it's
unnecessary. The berries aren't picked until they begin ripening. The
artificial dose of ethylene isn't needed to finish ripening them.
